To all who're it ancem."

Be it .known that I, BRYANT D. CAMPBELL,

I citizen of the United States, resid-in at Oak-- land, in the county- 0f Alamedaan State of 'Ca-lifornim-have invented certain new and useful Improvements in Coin-Controlled Attachments for Vendin -Machines; and I do hereby declare the foowing to be a full,

clear, and exact description of the same.

This invention relates to coin controlled .attachments for telephones or other vending devices.

One'of the objects of the invention is to rovide a device of this character, particu lhrly-adapted for telephoneservice wherein it is desirable, in the event of failure to render depositor.

the service paid for-by the coin deposited therein, that the coin shall be returne to the Another object of the invention is to provide a device wherein the signal to central is made through the intervention of a coin.

Another'ob'ect of the inventionis lto provide means w erein it will 'be impossibleto give a signal by. merely completing the-circui't exterior to or independent ofthe'coi n.

Another. object of the invention is to provide such a device as will not only return the coin in non-effective operations but. will also keep tally oil both effective and non-effective operations.

. In devices of the characterv of thej'presentinvention, simplicity,- certainty of operation and cheapness of construction arematters of the first importance as they areusually used knowle c. v

Still another object therefore, of the'present invention is to provide a: coin controlled attachment for tele' hones; sim ler, cheaper and more certain 0 operation t an those at present in.use. 4

These objects are accomplished by means v,of the devicesil lustrated in the accompany ing ldraw-in'gs in which gure 1 is a front elevation of the device, Y portions being omitted ,to more clearly illus-y trate the registerin devices. Fig. 2 is a sectional elevation; ig. 3' is across. section through' X-'X of Fig. 2. Fig.4 'is a detail showing the coin .suIEort and'yoperating 'g. 5 is afront iew mechanism therefor.

a signaling device-1 A spa-mg paw-1:20 is securedto the shaft 3 adapted to.

of Fig. 4, Fig. 6 is a detail showing the coin carrier. Fig. 7 is a detail showing the pawl connection with the registering device.

Referring .to th'e drawings, 1 is a suitable frame or casing provided with.'a coin carrier 2 preterably secured to a shaft 3 which is j-ournaled in the casing 1. The shaft .3 is provided with a gear; adapted to eng e witha rack .5 secured to an opera-tin hanfie 6. The handle -6 which extendstc t e exterior of the casing'm'ay be operated in onedirection b a sprm 7. The carrier 2 is pm vided on itsinn'er side with a recess on: :pocket 8. A suitable coin-chut'e or slot9 is provided adapted to direct a coin into-the reeessS.

Pivoted to the cash: 1 is a hook lever 10.

The record 16 is connectedbyany suitable means, with one pole of a'battery 17 or other source of electrical energy. The other *P 13 s also prcvide'jd, attached to thecarrier-2.

of the battery 17 may be connected with the casing 1 by-meansofthe bindingpost-IS. I 19 re resents alight, hii'zzer, hell or other snitcontrolled engage with a ratchet-Wheel 21 of. a suitable.

counting or'regis'teringdevieepreferably conp sisting of a train of ratehetor gear wheels, meshing intoor'en-gaging'with each other. These are provided with suitable or pointers and numerals or other appro riate- ,mdices; all of which are fully shown in i gs. 1

and 13. Below the carrier -2 is mc e a guide 22 -le'ading to theoutside of t casing 1 and-preferably connected with this guide is a .second guide 23 leading to a suitable coin box or r cept'acle (not shown), thus formingla bi-.

Suitable means may be provided for subtracting the operations of the registering de "'vice 32 (which registers the number of coins returned) from that of registering device 21.

These are shown in Fig. 1 as consisting of a -pivoted.-lever 33- adapted tovbe operated by ratchet, Wheel 32. Connected with the lever jof link 34 out of engagement with ratr ratchet wheel32; Below'the guide 3 5 tacle '89 for the rece tion of a coin;

Pressing the hand e b, ownward rotates car- "centra rier 2 and moves thecoin into engagement with the hook lever 10- thus'raising it out of the path of the-recess 8. The carrier is thus permitted to make its full movement, during which it brings the tapfiet 18 into electrical contact andmechanica y operative engagement with the member 15 thus partially rotatin the record 16 causing the words denoting the value of the coin to be carried to The tappet 13 by engagement with the member 15. closes the circuit and operates the signal 19. The coin in the meantime has been deposited in the guide 22 rest- 1 ing'upon the lever 24-. The return movement of the carrier 2, which-is effected by the spring 7 on handle 6, brings the arm il with its pawl 12 back past the coin and-the recess '8 to its normal position. hen the signal is given the feentra asks for number wanted and for' any reason the same is not given,-

the ,central closes switchBO thereby com; pletin the circuit and magnetizing thee-oils 28 which operates the plate 25 and causes the Pivotally secured to an ex tension of plate, 25 is a spring controlled pawl .31 adapted to engage witha ratchet wheel 32 which isi'one' of the. members of a second counting for-registering device, similar to that already desc thus allowing the same to drop through the guide 22 out of the casing upon the plate 39. In normal operations where the switchis given, the next movement of the carrier 2 brings the pawl 1.2 into engagement with the coin in the guide 22 pushing it into guide 23 and thence to the coin-receptacle.

During the complete movement of the carrier, the pawl 20 on the shaft 3 engages with ratchet wheel 21 causing it to moveone tooth or number thereby registering the number of o erations of the carrier and consequently t e number of coins which would be in. the

ie providing none were returned by cer When. the plate 25 is moved downward, the pawl 31., secured thereto, 0 erates the ratchet wheel 82 and registers ,t 1e number of coins returned. The difierence betwe 1 the numbers indicated by the registers-wni be the number o'f'coins contained in the coin receptacle. When however the subtracting connections are used,. the return coin and the main counter the correct number of switches received and paid for.

An attempt to operate the device without the coin produces the following results The handle is pressed downward causing the carrier 2 to rotate until the recess ,8 engages with the hook lever 10 thereby preventing further rotation of the carrier and movement of handle. This amount of movement is not withthe member 15 nor the pawl 20 into engagement with the ratchet wheel 21. Thus the device gives no signal and consequently does not register.

- It will be seen person will be unable to signal 1eentral and coin usedin that particular. telephone. She thereby knows at once What district iswanted and if the proper telephone is being used by thedepositor.

Much annoyance anddelay is prevented by the depositor being first compe led to deposit a com before he signals central. The advantage ofrcentra being able to return the coin when no service is rendered is obvione. As the device registers the number of lever 24 to be'removed from beneath the coin will therefore unable to get any service counter shows the'number of coins returned sufiicient to bring the tappct 13 into contact from the .foregoing that a ing the district wanted or the value ofthe operations and the coins returned, and sub-- tracts one from the other, the

This will be partic'ularly the case where one company owns a 1arge number'of sdch' machines'and different the-essential nature of this invention. ifact-whenused as a vendingmachine for "car peol'e open} the 'machines to 5 replenish the sto'c andremove the coins. v15
